Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With Butyl 2-Propenoate, n-(Hydroxymethyl)-2-Methyl-2-Propenamide And 2-Methyl-2-Propenamide CAS NO 28935-10-6 is a specialized acrylic copolymer designed to deliver high-performance characteristics in demanding industrial formulations. This multi-component polymer is engineered to provide an excellent balance of film-forming properties, adhesion, and chemical resistance. It is a critical raw material for manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product durability and functionality. Its reactive amide and hydroxyl functionalities make it particularly valuable for creating cross-linked networks with superior mechanical properties.

Application

• Industrial Coatings: Used as a key binder in high-performance metal, wood, and plastic coatings requiring excellent weatherability, gloss, and hardness.
• Adhesives & Sealants: Serves as a primary polymer in structural and pressure-sensitive adhesives (PSAs), providing strong adhesion to diverse substrates and enhanced cohesion.
• Textile & Leather Finishes: Employed in coatings and binders to impart water resistance, durability, and a soft hand feel to finished fabrics and leather goods.
• Paper & Packaging Coatings: Enhances the surface strength, printability, and water resistance of paperboard and packaging materials.
• Automotive Refinish: A component in automotive repair paints and clear coats, contributing to fast drying times, high gloss, and chip resistance.
• Construction Chemicals: Incorporated into cement modifiers and waterproofing membranes to improve flexibility, adhesion, and long-term durability.

Quality Control

Our 2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, acid value, and glass transition temperature (Tg) to ensure consistent performance and batch-to-batch uniformity. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all specification results. Our production adheres to ISO 9001 standards, and the product is compliant with global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity due to moisture or solvent loss.
